A delayed war would not make German commerce raiding easy

Would Germany still send surface commerce raiders out if a war delayed until 1942 faced a much stronger Royal Navy?

Possibly, especially Panzerschiffe, but the enlarged Royal Navy would make the operation doubtful and the result depends on what Germany could actually finish in the extra years.

Germany would probably hesitate to send cruisers and pocket battleships into an ocean patrolled by the expanded British force in the question. The decisive uncertainty is what German yards could complete during the extra three years. Panzerschiffe, including a possible second generation, might still be risked. The counterfactual therefore turns on industrial capacity and force generation rather than an assumption that a later start automatically improves German operational freedom.
